No. 267,006 1 Claim. (Cl. 133-8) This invention relates to machines used for automatically accomplishing collation and packaging of coins or the like, and more particularly to a specific structure for such purpose, said structure being extremely durable and highly reliable in operation.

Whereas rotatable discs or washers commonly used in coin handling machines for effectuating the coin conveying function must frequently \be replaced because of poor wear resistant properties usually associated with materials capable of frictionally conveying said coins to the desired region, the instant apparatus as herewith disclosed is provided to obviate the difficulty heretofore encountered.

Other advantages and objects of the invention will be set forth in part hereinafter and in part will be obvious herefrom or may be learned by practice of the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claim.

The invention consists in the novel parts, construction, arrangements, combinations and improvements herein shown and described.

The accompanying drawings referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

FIGURE 1 is a side elevational view of the respective elements of the present apparatus, a top view of the rotatable disc being shown therein;

FIGURE 2 is an expanded perspective view of the rotatable disc, the housing therefor, and the driving means associated therewith; and

FIGURE 3 is a cross-sectional elevational view of the assemblage of elements shown in FIGURE 2.

An object of the invention is to provide novel means whereby coined currency may be expediently collated and packaged in wrappers conventionally employed there for.

Another object of the instant invention is the provision of a rotatable disc possessed of extremely high wear resistant and frictional properties, said disc being operative in conveying coins to the wrapping region.

A further object of the present invention resides in the provision of an improved rotatable disc which is non- .frayable, high of tensile strength, extremely durable,

which is very reliable in operation and which may be readily replaced after unexpectedly long periods of performance.

It will be understood that the foregoing general objectives and the following detailed description as well are exemplary and explanatory but are not restrictive of the invention.

A general understanding of the arrangements and location of the novel device as shown in FIGURE 1 discloses the cooperation of the elements of the operative assembly of the coin Wrapping apparatus designated generally by numeral 1; said assembly being essentially comprised of horizontally disposed rotatable platform 2, said platform being circular in shape, a wall 4 arranged peripherally of said platform 2 and spaced therefrom, said wall projecting upwardly of surface 6 of said platform to thus provide a retaining structure about said rotatable platform. Accordingly, then, it will be appreciated that coins 8 supported upon said platform will, when said platform is rotated by electric motor or driving means 10, be tangentially directed from said rotatable platform and will thereby be ejected through passagelZ provided through said wall 4, and therefrom upon stationary platform 14 which is positioned beneath rotating disc or washer 16 and spaced therefrom at 18, said space 18 being slightly smaller than the thickness of the individual coins 8.

Passage 12 being slightly larger than said individual coins 8, will therefore permit the passage of coins in single file, each coin being continually deflected by wall 4 until such time as it enters said passage 12 therein and is carried by its own momentum over stationary platform 14 and beneath rotating disc 16 wherefrom it is accelerated and directed against an upwardly projecting wall as shown provided endwise of platform 14. Upon striking said wall each said coin 8, responding to the force of gravity, descends through outlet passage 20 and into wrapper 22 supported therebeneath within cup 24 and is collated within said wrapper as illustrated.

Referring now to FIGURES 2 and 3, it. will be observed that rotatable disc 16 is fixedly mounted between gear wheel 26 and backing plate 28 and is of diameter greater than said gear Wheel and said backing plate. Rotatable disc 16, being provided with an axial opening 30 and pin receiving bore 32, is pre-positionable upon boss 34 and pin 36, respectively, said boss and pin being provided integrally upon said gear wheel 26. Bolt 38 extending through opening 40 provided axially of backing plate 28, extends through said opening 30 and is threadedly received within threaded passage 42 located axially of said boss 3-4 and said gear wheel 26, head 44 of said bolt being countersunk and supported within opening 40 of said backing plate 28.

Gear teeth 46 provided peripherally of said gear wheel 26 engage gear teeth 48 of gear 50, said gear 50 being driven by electric motor or other suitable driving means 52 to thus rotate rotatable disc 16 in the counterclockwise direction as shown by arrow 53 in FIGURE 1 of the drawings.

Rotatable disc or washer 16, by dint of abrasion with said coins 8 normally require frequent replacement, where constructed of materials employed heretofore and in accordance with the teachings of the prior art. That is, natural and synthetic rubber, homogeneous laminated or fiber reinforced, nylon or FEPfluorocarbon (Du Pont trademark Teflon), as conventionally used in the construction of rotatable discs or Washers within the purview of the present invention, have been subjected to wear, unraveling and fraying in accordance with known expectations, replacement of said discs being required and accomplished after relatively short intervals of use.

The material of which the presently disclosed rotatable disc is formed, however, affords an unexpected and un obvious effect in that although of the same size and shape of conventionally utilized discs, the present disc, an urethane elastomer having a hardness ranging between 50 to Shore. durometer and being homogeneous throughout, will endure substantially in excess of fifty times the wear endurable by discs formed of materials heretofore employed.

Urethane elastomers are produced through the reaction of polyisocyanate and polyhydr-oxy compounds to form a long chain, essentially linear macromolecule. Although, as aforestated, the preferred rotatable disc construction according to the present invention is of the urethane elastomer in homogeneous form, a coating of the elastomer over any of the aforesaid heretofore used materials also renders a rotatable disc possessed of attributes unexpected and representing a substantial advance in the coin handling machine art.

Although the preferred and alternate embodiments of thedevice have been described, it will be understood that Within the purview of this invention various changes may be made in the forms, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consists in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claim.

What is claimed is:

p A coin handling machine comprising an horizontally disposed rotatable platform, first driving means associated with said rotatable platform, a stationary platform adjacent said rotatable platform and in the same plane therewith, a first upwardly projecting Wall provided between said rotatable platform and one end of said stationary platform, a passage within said Wall communicably relating said platforms, a rotatable disc normally disposed with respect to said stationary platform, said disc being formed of fibrous material having a polyurethane elastomer coating, the latter having a hardness References Cited by the Examiner UNITED STATES PATENTS 11/15 Bock.
